@kepano I'm a big fan of the excalidraw plugin, but it still feels a bit clunky to use sometimes and I suppose the learning curve might be a bit too step for new comers to obsidian.
I'm convinced that #obsidian would greatly benefit a native integration of a drawing tool (which could be some sort of upgrade of the current canvas plug-in)
in other words: frictionless inline drawing canvas that you could add and edit without leaving the note you are working on. The ultimate combination of text and visual :) I imagine it especially powerful on touchscreen tablet-like devices and e-ink computers.
